The present invention relates to a novel device for rapidly and correctly producing sign writing and the like by means of lettering guides, and the invention essentially consists in the particular construction, cornbination and cooperation of parts, as will now be fully described in connection with the accompanying drawings, in which Figure 1 shows a plan view of the complete device; Fig. 2 represents a section on line CD of Fig. 1, and Fig. 3 a similar section on line A-B; Fig. G-H of Fig. 2; Fig. 5 represents a fragmental view of a lettering guide with the stylus point in operative position.

The frame is composed of the longitudinal members 1 and 2, and the cross-membersB and 4; supported on the swiveled rollers 5 (Figs. 1 and 3) and can thus easily be moved about over the surface to be Written upon without damage to the latter.' Pointed thumb screws 6 in the cross member 3 serve to fix the frame in the desired position on the writing surface, and the cross-members 3, 4 are provided, intermediate their extremities, with hinges 7 for folding up the frame when not in use. The longitudinal frame members 1,

2 are provided with slots 8 (Fig. 1) in which operate the screw bolts 10, which have a square portion 9 and which can be tightened on the respective longitudinal members by manipulation of their nuts 12. The sliding bars 11, which extend parallel to the cross-members 3, 4c, are provided in their angularly bent-off extremities with holes through which pass the set screws 10. Just within the bent extremities these sliding bars are provided with holes for receiving the screw bolts 13 2) with heads 14. A clamping bar 15 is provided for each sliding bar and the two bars, termed clamping member, are operatively connected by the screws 13. Lettering guides 17 (Figs. 1, 2 and 4:), in which a pattern, letters, numerals, or other characters are cut through, are to be inserted in between these two bars and are then clamped fast by tightening the screws 13.- The lettering guides 17 are angu- LETTERING-GUIDE;

Depending upon the incriptions or other representations to be produced the sliding clamping members are shifted up or down Within the frame and are finally locked in position by the nuts 12. Scales on the longitudinal members 1, 2 facilitate the positioning of the individual clamping members. A stylus 22 is inserted into the cut-outs in the lettering guides to produce their counterparts on the underlying writing surface.

The described invention enables an unskilled writer and even a one-armed one to turn out quick and accurate work.

What I claim is v 1. In a device of the class described, the combination of a frame comprising longitudinal members and sectional transverse members, hinges connecting the respective sections of each transverse member. the longitudinal members having slots, means for positioning the frame, bars extending over the longitudinal members, means extending through the slow for securing the bars to the longitudinal members, clamps extendingoverthe face of each. bar, means for fastening the clamps to the bars, and a plurality of lettering guides interposed be tween the bars and the clamps, each guide Patented Nov, 19,1918. enem sa etate:- m 9 a0e i I frame clamping means extending through the slots to secure the bars in position, ro11- ers on the frame, screws extending through the franie'to fasten the same to a support, clamps fitted on the faces of the bars, lettering guides interposed between the latter clamps and the bars, the guides havin transverseseats to receive the bars when the clamps are tightened.
